fix(*): make sure elaborator and type_checker use the same "rules" for treating opaque definitions
...
This is a big change because we have to store in constraints whether we can use the "relaxed" rules or not.
The "relaxed" case says that when type checking the value of an opaque definition we can treat other opaque definitions in the same module as transparent.

feat(kernel/converter): add eta-expansion to converter, this is important when terms contains metavariables
...
For example, consider the unification constrains
fun (x : A), f (?m x) =?= f
Eta-reduction is not applicable since (?m x) is not a variable.
However, if we eta-expand the left-hand-side, we get
fun (x : A), f (?m x) =?= fun (x : A), f x
which is reduced to
(?m x) =?= x

refactor(kernel): remove 'let'-expressions
...
We simulate it in the following way:
1- An opaque 'let'-expressions (let x : t := v in b) is encoded as
((fun (x : t), b) v)
We also use a macro (let-macro) to mark this pattern.
Thus, the pretty-printer knows how to display it correctly.
2- Transparent 'let'-expressions are eagerly expanded by the parser.

refactor(kernel/converter): implement eta in whnf instead of is_def_eq.
...
Without cumulativity, we do not have problems with Eta at whnf anymore.
When we had cumulativity, we could not not simply reduce
(fun x : A, f x) ==> f
This step is correct only if domain(f) was definitionally equal to f.
Here is a problematic example for systems with cumulativity
Given, f : Type.{2} -> Bool
(fun x : Type.{1}, f x)
